风力发电是技术较成熟、*商业潜力的新能源之一。无锡风力风机制造有限公司目前，我国已进入大规模开发利用阶段，在2010年底超过美国，成为世界*大风电装机大国。但我国的风电机组技术水平较差，国内风电机组约80%的风力发电机组，存在着无法实现低电压穿越、难以满足电网并网要求的问题。低电压穿越和零电压穿越是风电设备的核心技术，是决定风电机组能否安全并网的关键指标。低电压穿越，如同在电网这条高速公路上，行驶中的风电遇到公路流量大幅波动或路障时，不是选择迅速靠边停车、引起交通混乱，而是开辟一个窄的通道，以保障公路有效通行。（图/文http://www.wxfengli.com/）

Wind power is a more mature technology, most of the commercial potential of new energy sources. At present, China has entered a stage of large-scale exploitation, at the end of 2010 more than the United States, to become the world's first wind power installed power. But in our country, the technology of wind turbine was poor, the domestic wind turbines approximately 80% of the wind turbine, there are unable to realize the low voltage ride-through, difficult to meet the requirements of the grid. Low voltage ride-through and zero voltage crossing is the core technology of wind power equipment, is to determine the wind turbine can be safely combined key indicators. Low voltage ride-through, as in the power grid this freeway, running in the wind flow fluctuations or encounter highway barricade, chose not to pull over quickly, caused traffic chaos, but open up a narrow channel, in order to ensure the effective traffic highway.
